Abstract (en)
The present invention relates to a light emitting device which emits light upon impingement of thermoelectrons on a front panel having fluorescent elements. In each bonding surface of a spacer (3) which is bonded to both front (1) and rear (6) panels, a positional deviation or displacement of the spacer with respect to the front panel, the rear panel or a shielding electrode is prevented by emplying a stepped portion on said rear panel (6) fitting with said spacer (3), whereby there is obtained a light emitting device of high accuracy free of variations in luminance, and it is made possible to reduce a dead space between adjacent light emitting devices and thereby attain a display of high resolution. In order to obtain such display, the front panel and the spacer, as well as the rear panel and the spacer, are respectively bonded through premolded frit glass (21). Further embodiments include a method of fixing an anode by employing a plurality of elastic pieces on the outer periphery, said pieces being in contact with the inner side faces of the spacer and electrode leads having thermal expansion properties matched to the substrate and rear panel.
